MWSC One-Design 60 Racing
One-Design 60 provides a fun and inexpensive format for slope racing. The intent is to keep aircraft performance equalized, inexpensive to build and easy to fly in a variety of wind conditions. If you build a trick plane to outwit the rules, you may end up watching instead of flying, at the CD’s discretion. If you need an interpretation of the rules, call the CD before you build it.
Open to any plane, meeting the aircraft specifications below.
There is a limit of ONE entrant PER FREQUENCY in this event. See Pre-Registration page for details.
